I just bought an Eden WT-600 cheap!!! 1 dollar : 1 watt!! I have a question about it though. It has two channels at 300 watts at 4 ohms. I have 2 avatars 115 kappa 4ohms and 210 neo 8ohms. Is it safe to use these cabs in each separate channel? Can I use the bi-amp feature or should they be run at full range? If this Is a problem, I can replace my Kappa 15LF with an 8ohm 300 watt speaker from my BXR 300C combo (unless the tweeter impedence factors in). Thanks for the advice.
